What is the best speaker for an airport in Belo Horizonte?
Quick answer
For an airport in Belo Horizonte, the right SSOUNDS solution combines EN 54 / BS 5839-8 compliant voice alarm and PA, with ceiling loudspeakers (CL6, CL8) for concourses and retail, slim column loudspeakers (LC8.2, LC16.2) for reverberant halls and gate areas, and P series install loudspeakers (P4, P5, P6T, P10T, P12T) for larger spaces. SSOUNDS designs and installs across Belo Horizonte, using A series networked amplifiers with DSP and Dante for zoned paging, line supervision and redundant amplification.
Airports demand intelligible speech in challenging acoustic environments: large reverberant halls, high ambient noise from aircraft and crowds, and the need for zoned paging that reaches the right area at the right time. The primary selection criteria are EN 54 / BS 5839-8 compliance for voice alarm, STI (Speech Transmission Index) performance, line supervision, and redundant amplifier paths. SSOUNDS approaches each airport project by first modelling the space with AI-assisted acoustic prediction, then selecting loudspeaker types and quantities to achieve target STI and SPL coverage.
For terminal buildings, SSOUNDS recommends a layered approach. Ceiling loudspeakers from the CL series (CL6, CL8) suit check-in halls, retail and circulation areas where even coverage and low visual impact matter. For tall, reverberant spaces such as departure lounges and gate piers, slim column loudspeakers (LC8.2, LC16.2) provide controlled vertical directivity to keep sound on the listeners and off reflective surfaces. Where higher SPL or longer throw is required, P series install loudspeakers (P4, P5, P6T, P10T, P12T) offer point-source coverage, with T models operating on 70/100 V lines for long cable runs and simplified supervision. M series point-source boxes and subwoofers can reinforce larger public areas or baggage halls if needed.
Sizing and zoning are critical. SSOUNDS engineers calculate loudspeaker spacing from ceiling height, target STI and ambient noise, then define zones that align with airport operations: check-in, security, gates, baggage reclaim, and outdoor areas. A series networked amplifiers with DSP and Dante provide the processing, routing and redundancy, with line supervision and backup amplifier paths to meet life-safety requirements. The result is a system that delivers clear, reliable announcements and meets the standards airports require.
SSOUNDS designs and installs across Belo Horizonte, with engineering support from our UK and European R&D and our African operations. For projects in Brazil, we ship and support internationally from our bases in the United Kingdom, United States, Nigeria and Ghana.
